Like Mother, Like Daughter

Brynna: Can I have some of that, Mommy?

Me: Some of what?

Brynna: Some of that chocolate in the box over there on the table!

[Let's note that this box has come from Barcelona, it has not been opened, Alex told me about it when Brynna was not around, and it does indeed contain fancy chocolate but there is no way that B could know this, since it doesn't look like any other chocolate box she has ever seen!]

Me, innocently: How do you know what's in there?

Brynna, with withering look: I just KNOW that there's chocolate in there.
